Final project: Water problems(sudan)



Sudan water problems

Water is the source of life, it is very important to human, plants and animals to survive. A lot of countries have water problems, that’s because they are a poor countries and they have weak economy. Some of those countries don’t have sanitation and they dispose sewage water in sea. Other countries have drought and floods; this makes a big deal in the water shortage. The increase in population number and the rising incomes over the time are other reason for water shortage. Some countries have a very hot weather in summer witch will cause the lands to be dry. A lot of countries have large industries and so many farms; they both consume large quantities of water daily. The shortage of water in those countries will cause a lot of problems that lead to death of living organisms. Many industries rely on water in their industrial process, water shortages lead to stop the industries process. Farmers are depending on clean water in plant, and the water shortage cause plant to wither. If they didn’t find a solution a civil war may happen between the powerful and poor citizen.

Sudan has water problems, this problem is partially blamed on the land since it has very low rain and it’s located in very hot and dry place. The Nile River is the main source of water for Sudan and not a lot of people have access to it due to the structure of the land, even if the people have access to it, the Nile itself have shortage. In hot season water may evaporate limiting the capacity to supply water to the people; rainfall in Sudan is random and happens in short season of the year which is a big part why Sudan has water problems. On the other hand there is the current violence taking place in the region which is limiting the water for Sudan’s people. There is competition between Arab and non-Arab farmers they are fighting about who should use the land (LoveToKnow, 1996-2012). About 80% of the people work in agriculture and agriculture is about 40% of the market and accounts for 97% of the water in use. Water is not just income and a job it’s life itself (Dr. Paul J, 2010), these days this situations grows more violent people have been forced to leave their homes to live in refugee camps or other countries, some of them had to give up their land so they can move away from this conflict (LoveToKnow, 1996-2012).
Shortage of water and Unclean water spreads diseases such as cholera and infant diarrhea but if water is managed carefully there will be enough water and clean water in Sudan. There are solutions to the shortage of water in Sudan like repairing old water systems, controlling water utilities using less water for the agriculture by using drip irrigation and focusing more on watershed management. they can increase the price of water to the rich people and maintain the price to the poor people to gain more money to build desalination plants and to be operated with a global team and trained local operators The General solution can be by the main source which is the Nile river if they have more access to the water they will not have shortage of water due to the hot weather which will evaporate the water or because of less of rainfall. There are other solutions for the country itself is to stop the civil war between them because the war makes some places have water and some other cannot access it and sometimes it can cause pollution to water which will cause some diseases or death to the people drinking it and to start to educate the people and teach them not to drink the unclean water because a lot of children they are dead from shortage or unclean water before they reach 5 years.

A Smartphone is a mobile phone built on a mobile computing platform, with more advanced computing ability and connectivity than a feature phone. The first Smartphone was the IBM Simon; it was designed in 1992 and shown as a concept product. It was released to the community in 1993 and sold by Bell South. The mobile phone had many features such as a calendar, address book, world clock, calculator, notepad, email client; it could also send and receive faxes, and games. It used touch screen to select telephone numbers or create faxes and memos, text was entered with a unique on-screen keyboard. Today’s Smartphone serve as a portable media player, compact digital camera, and GPS navigation unit. Modern Smartphones include a high resolution touch screen, web browsers and high speed data access via Wi-Fi and mobile broadband. In 1996, the Nokia 9000 was released, it was characterized by clamshell design with a feature phone display, keyboard and user interface, high-resolution display of at least 640x200 pixels and a PDA use interface under the flip-top. In 1998, it was followed by a Nokia 9110 and in 2000 by Nokia 9110i, with improved browsing capability (Wikipedia, 18 April 2012). Some people would say without communication we are hopeless, different communication system such as mobile technology, telephony, radio and TV is so important in our lives, it is often used in our daily dealings with people around us, entertain us, and aid us in our businesses and many more. Interestingly the telephone system is one of the most useful communication devices since it was invented in 1877 until now (emilgen, 2011).

By 1904 there were over three million phones in the US, still connected by manual switchboard exchanges. By 1914, the US was the world leader in teledensity and had more than twice the teledensity of Sweden, New Zealand, Switzerland, and Norway. The longest lasting physical style of telephone was introduced in the early 20th century, including Bell’s model 102. A carbon granule transmitter and electromagnetic receiver were united in a single molded plastic handle, which when not in use sat in a cradle in the base unit; it had direct connection of the receiver to the line, while the transmitter was induction coupled, with energy supplied by a local battery. The coupling transformer, battery, and ringer were in a separate enclosure. The dial switch interrupted the current very briefly disconnecting the line 1-10 times for each digit. In 1960s the touch-tone signaling started replacing the rotary dial (Wikipedia, 14 March 2012).Theodore N.Vail led the Bell Companies to create his “universal service” which was completed in 1915 from New York to San Francisco. Vail also used the wireless system to begin overseas cable installations, connecting the US to other countries. In the late 1940s the first commercial mobile phones were installed and microwave radio was introduced for long distance use. The scientist at Bell Labs invented the transistor and the course of history changed, in 1948 there were 30 million phones in service. Fredrick Kappel brought technological advancement to the system. New phones were introduced like the Princess phone which was in 1959, in 1963 the first Touch-Tone phones were released and in 1965 the Trimline was commenced. By 1971 there were over 100 million phones in service (Gregory Russell, 1998).

                                             History of the telephone


In March 10, 1876 Alexander Graham Bell yelled his famous words “come here Mr. Watson, I want to see you” using a liquid transmitter and an electromagnetic receiver and from that day telephones were invented.  In July 1877 Alexander Bell and Watson started making telephones by the end of 1877 there were three thousand telephones in service. Theodore Vail was the general manager of the Bell Company he helped in expanding the business by developing long distance services. In 1877 Thomas Edison developed a carbon-button transmitter that was better than Bell’s transmitter and the invention of the telephone expanded more and more. In 1878 a manual switching board was introduced that allowed many phones to be connected through a single exchange (Gregory Russell, 1998). People have been trying to invent the telephone for years before Alexander Bell. The telephone came out from the creation of electric telegraph. In 1804, Catalan polymath and scientist Francisco Campillo built an electrochemical telegraph, and an electromagnetic telegraph was created by Baron Schilling in 1832. In April 9 1839, the first commercial electrical telegraph was made by Sir William Fothergill, it ran for 13 miles. In 1837, Samuel Morse invented another electrical telegraph that went across 2 miles which led to the Morse code we use today. During the second half of the 19th century inventors tried to find ways of sending multiple telegraph messages over a single telegraph wire by using different modulated audio, their efforts to develop acoustic telegraph led to the invention of the telephone( Wikipedia, 14 March 2012).

Carbon Emissions
Carbon emission is creating a problem because the amount of carbon in the atmosphere has doubled in the last 30 years. Carbon emission is created by the people who are using fuel to produce electricity and power their cars or using energy.
There are many levels of carbon emission in the world,  especially in the Middle East and North Africa. It also depends on how developed oil-rich countries are because it is related to industrial output. There is an estimation that the Arabian Gulf countries are on top of the list globally.

The environment agency-Abu Dhabi has launched a project to analyze the Emirates’ emissions so the government can develop strategies to reduce the level of emissions and to build areas that absorb gases such as wetlands and mangroves.
